Hi,
the latest version of the plugin wasn't able to display private photos on the "photosets" tab. After digging into the code a bit, I found the reason: the auth-token for flickr is missing in the $params array passed to the flickr call. When I added user_id and auth_token to the array it worked.
So I changed lines 2020-2022 of FlickrManager.php to this
2020 'page' => $page,
2021 'user_id' => $settings['nsid'],
2022 'auth_token' => $settings['token'] );
and now private pictures are displayed on the photosets tab.
